[dpdk-dev] [PATCH 40/40] examples/pipeline: add VXLAN encap example

Cristian Dumitrescu cristian.dumitrescu at intel.com
Wed Aug 26 17:14:45 CEST 2020


Add VXLAN encapsulation example to the pipeline application. The VXLAN
tunnels can be generated with the vxlan.py script. Example command
line: ./build/pipeline -l0-1 -- -s ./examples/vxlan.cli

+ * Assumption: When read from the table, the outer IPv4 and UDP headers contain
+ * the following fields:
+ *    - t.ipv4_total_len: Set to 50, which covers the length of:
+ *         - The outer IPv4 header (20 bytes);
+ *         - The outer UDP header (8 bytes);
+ *         - The outer VXLAN header (8 bytes);
+ *         - The inner Ethernet header (14 bytes);
+ *    - t.ipv4_hdr_checksum: Includes the above total length.
+ *    - t.udp_length: Set to 30, which covers the length of:
+ *         - The outer UDP header (8 bytes);
+ *         - The outer VXLAN header (8 bytes);
+ *         - The inner Ethernet header (14 bytes);
+ *    - t.udp_checksum: Set to 0.
+ *
+ * Once the total length of the inner IPv4 packet (h.ipv4.total_len) is known,
+ * the outer IPv4 and UDP headers are updated as follows:
+ *    - h.outer_ipv4.total_len = t.ipv4_total_len + h.ipv4.total_len
+ *    - h.outer_ipv4.hdr_checksum = t.ipv4_hdr_checksum + h.ipv4.total_len
